Definitions

• the present invention relates to plastic sheets, processes for their production and their use for sealing buildings.
• EP 0 428 851 describes plastic sealing sheets which are made up of flexible polyolefins.
• plastic sealing sheets At elevated temperatures, for example in summer when there is strong solar radiation, these plastic sealing sheets have the disadvantage that they can be damaged, in particular perforated, during extreme mechanical loads during processing.
• plastic sealing sheets also have a relatively large linear coefficient of thermal expansion, which, depending on the temperature differences, for example day / night, summer / winter, can lead to the formation of waves in the surface of the plastic sealing sheets when the plastic sealing sheets are laid.
• EP 0 428 851 also describes the further prior art, which with this reference is also considered to be disclosed herein.
• a new material is to be made available which has the requirements mentioned in EP 0 428 851 and additionally has improved mechanical properties, in particular in the heat, and a reduced linear mechanical expansion coefficient.
• the new plastic sheets with reactor blends which are made up of inexpensive starting materials (monomers), are to be produced. These raw materials should also have a more favorable energy and eco-balance.
• the new plastic sheets are said to have an even better price / performance ratio than EP 0 428 851.
• reactor blends selected from the group consisting of polypropylene copolymers and ethylene- ⁇ -olefin copolymers can be used for the production of plastic webs with an upper layer, a lower layer and an intermediate substrate, the upper layer and penetrate the underlayer in such a way that they are welded together.
• connection and finishing work such as borders, corner formations, roof edge closures, etc.
• the thickness of the web can be reduced, which leads to an improved price / performance ratio and a saving in raw materials (resources).
